Interesting that you speak highly of the four sound cards. I found them very disappointing and was anxious to sell them and did to a fellow in Australia. I was told how wonderful the strings were in one of the boards because I was interested in better string sounds than what was in the KN7000. I found no strings better than what was in the keyboard. I was looking very much forward to the number 4 board because it was supposed to have good sax and trumpet sounds. Totally disappointed. It is a case of different strokes for different folks with these boards. You can pretty much change the sounds in edit sound to what is on these boards. Technics just did this for everyone and put out these boards.
While on the subject, I have always smiled at many on the forum that have found the "Concert Grand" sound so wonderful and much better than the "Piano" sound. All one has to do is change the brilliance of the "Piano" and you have the Concert Grand sound. Nice flimflamming coming from Technics.
